IEC 61526:2010 pdf free download.Radiation protection instrumentation – Measurement of personal dose equivalents Hp(10) and Hp(0,07) for X, gamma, neutron and beta radiations – Direct reading personal dose equivalent meters.
IEC 61526:2010 applies to active, direct reading personal dose equivalent meters and monitors used for measuring the personal dose equivalents Hp(10)and Hp(0,07 )for X gamma, neutron and beta radiations.
For the personal dose equivalent H(10)or the personal dose equivalent rate Hp(10)and for X and gamma radiations, two minimum rated ranges for the photon energy are given. The first from 20 keV to 150 keV is for workplaces where low energy X-rays are used, e.g., in medical diagnostic, the second from 80 keV to 1, 5 MeV is for workplaces where high energy X-rays and/or gamma sources are used, e.g., in industry. For neutron radiation the minimum rated range of neutron energy is from 0, 025 eV (thermal neutrons)to 5 MeV. The rated ranges can be extended to all energies covered by the respective standards for reference radiation fields.
For the personal dose equivalent H,(0, 07) and for X and gamma radiations, a minimum rated range for the photon energy from 20 keV to 150 keV is given and for beta radiation, th minimal rated range is from 0, 2 MeV to 0, 8 MeV. The rated ranges can be extended to all energies covered by the respective standards for reference radiation fields.
Examples of extended rated ranges are given in Annex C.
IEC 61526:2010 specifies requirements for the dosemeter and, if supplied, for its associated readout system.
This standard specifies, for the dosemeters described above, general characteristics, general test procedures, radiation characteristics as well as electrical, mechanical, safety and envi- ronmental characteristics. The only requirements specified for associated readout systems are those which affect its accuracy of readout of the personal dose equivalent and alarm settings and those which concern the influence of the reader on the dosemeter.
IEC 61526:2010 also specifies in Annex C usage categories with respect to different measuring capabilities.
IEC 61526:2010 does not cover special requirements for accident or emergency dosimetry although the dosemeters may be used for this purpose. The standard does not apply to dosemeters used for measurement of pulsed radiation, such as radiation emanating from most medical diagnostic X-ray facilities, linear accelerators or similar equipment.
